           Summary: foreach scope does not call destructor
           Product: D
           Version: 2.008
          Platform: All
        OS/Version: All
            Status: NEW
          Keywords: wrong-code
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: gide nwawudu.com


Foreach statement (without braces '{}') and scoping objects, prevents the call
to the object's destructor. The code below outlines the problem.

Code
----
module main;

import std.stdio;

class MyClass {
    public:
        this()    {   
            writefln("Constructor");
        }
        ~this()   {   
            writefln("Destructor"); 
        }
    private:
        int myNumber;
};


int main() {
    writefln("1 - Start: OK dtor called");
    foreach (a; new int[1]) {
        scope x = new MyClass;
    }
    writefln("1 - End:   OK dtor called\n");

    writefln("2 - Start: dtor NOT called");
    foreach (a; new int[1])
        scope x = new MyClass;
    writefln("2 - End:   dtor NOT called\n");

    return 0;
};


Output
------
1 - Start: OK dtor called
Constructor
Destructor
1 - End:   OK dtor called

2 - Start: dtor NOT called
Constructor
2 - End:   dtor NOT called

This was fixed in DMD2.032 (probably a side-effect of the fix for bug 2925).
